EVERETT D. MOORE, OF BALTIMORE, MARYLAND, ASSIGNOR, BY DIRECT AND MESNEASSIGNMENTS, TO THE SINK OVERFLOW COMPANY, A CORPORATION OF MARYLAND.

ATTACHMENT FOR SINKS, STATIONARY WASI-ITUBS, AND THE LIKE.

Application filed June 5, 1912.

To all whom it may concern Be it known that I, EVERETT D. MOORE, acitizen of the United States, residing at Baltimore city, State ofMaryland, have invented new and useful Improvements in Attachments forSinks, Stationary Washtubs, and the Like, of which the following is aspecification.

This invention relates to improvements in attachments for sinks,stationary washtubs, and the like, and more particularly to an overflowattachment designed to maintain the water in the sink, washtub, orequivalent receptacle at some constant desired level.

The object of the invention is to provide a device which may be readilyand securely fitted in operative relation to the drainage opening, andas readily removed from its operative position; and which may be appliedto drainage openings equipped with perforated screening plates or todrainage openings equipped with cross frames.

A further object is to provide a device which may be readily dismantledfor the purposes of cleaning or repairs, and which is of simpleconstruction and may be put out at relatively low cost.

An embodiment of the invention is illustrated in the accompanyingdrawings, in which:

Figure 1 is a longitudinal sectional view of the device; Fig. 2 is asimilar view showing the attachment fitted over a drainage opening whichhas a perforated screening plate; Fig. 3 is a bottom plan view showingthe application of the device to said plate; Fig. 4 is a top plan viewof the attachment per se; Fig. 5 is a fragmentary longitudinal sectionalview showing the manner of applying the attachment over a drainageopening which has a cruciform frame or equivalent attachment fordrainage purposes; and Fig. 6 is a horizontal sectional view on the line66 of Fig. 5, looking in the direction of the arrow.

Similar characters of reference designate corresponding parts throughoutthe several views.

In the embodiment shown, the attachment consists of a tubular orcylindrical body 1 which is upright with relation to a base 2 and ispreferably dissociable from said base. As shown, the base 2 comprehendsa bell shaped mouth 2 terminating at its smaller Specification ofLetters Patent.

end in an upstanding flange 2 which telescopes into the lower end of thebody 1, and terminating at its larger end in a lateral annular flange ofangular cross section 2 which serves to retain a sealing gasket 3,

preferably held in place by rivets, and having a central opening of thesame diameter as the larger end of the bell 2% In order that the base 2may be securely seated with relation to the drainage opening A of thesink, washtub, or like recep-.

tacle, a retaining rod 4 is preferably employed. The upper end of therod 4 projects loosely through a relatively enlarged opening 5, in aguide piece 6. The latter may be conveniently made of substantial Ushape, and is provided at its upper ends with lugs 7 to engage over theupper edge of the body 1 and support said guide piece. The lower portionof the rod 4 is laterally offset and suitably inclined, as at 8, andadjacent the junction of the offset portion 8 and the upper portion ofthe rod 4, a hook like laterally projecting lug 9 is provided. In thisconnection it may be noted that the rod 4 may be formed with the portion8' The rod 4 is acted upon by a spring which tends to force said rodupwardly. As shown in the drawings, a retractile coil spring 10 isemployed for this purpose, one end of the spring 10 being, as a matterof convenience, secured to the guide piece 7, and the other end of thespring being secured at a suitable point on said. rod.

To center the rod 4 and to prevent any large obstructions from passingthrough the tube 1 and from choking the screening openings arranged atthe mouth of the drain opening, said rod is preferably provided with asuitable number, 6. 9. three, of laterally projecting lugs 11, and as amatter of convenience, the end of the spring 10 which is associated withthe rod 4 may be coiled about said rod immediately under said lugs, asshown.

Fig. 2 shows the device in use with a drainage opening which is equippedwith a perforated screening plate B. In such a case, the attachment isapplied in the following manner: The base 2 is held in concentricrelation to the plate B, and the rod 4: is depressed against the tensionof the spring 10 whereby its inclined portion 8 passes through thecentral opening of the plate B, this movement being continued until theapproximate junction of the inclined and straight portions of the rod tis reached. Thereupon, the downward pres sure on the rod 4 is released,and the spring 10, which has been tensioned by such downward pressure,exerts an upward axial pull on said rod which is effective to cause theinclined portion 8 to bind against the wall of the central opening ofthe plate B. The spring 10 not only exerts an upward pull on the rod 4,but consequent to the binding action referred to, it exerts a downwardpull on the body 1 and thereby serves to securely clamp the baseQagainst the plate B with the gasket 3 of said base in sealing relationupon said plate. It will be observed that the lugs 11 are of such extentthat they admit of the amount of lateral play of the rod 4 which isnecessary to allow the inclined portion 8 of said rod to pass throughthe central opening of the screen B. To remove the device from operativeposition, the body 1, and therewith the base 2, is lifted slightly fromthe screen B, and thereafter said body and base are slightly canted inthe lateral direction in which the part 8 projects, at which time thespring 10 moves the rod 4 upwardly and withdraws its inclined portion 8from the central opening of the plate B.

Fig. 5 shows the device in its application to a drainage opening whichis provided with a cruciform or equivalent straining frame C. In such acase, the base 2 is positioned over the drainage opening in suitablerelation thereto, and the rod 4 is depressed, as in the precedingexample, against the tension of the spring. Ultimately the finger 9 willpass one of the bars of the frame C and, as the rod tends to assume acentral and axial position, in the body 1 will engage under the barwhich it has passed, so that the spring will be held in tension tomaintain the base 2 seated against the mouth of the drainage opening. Toremove the device, the rod 4: is slightly depressed, and the device as awhole is shifted laterally to a slight extent, sufficient to disengagethe finger 9 from under the bar of the frame C, at which time the devicemay be lifted from position.

It will be apparent that the attachment may be very readily secured inoperative relation in connection with either type of drainage openingdescribed, and may as readily be removed. When the attachment is inoperative relation, its lower end, which contacts with the mouth of thedrainage opening, establishes a secure seal against the passage of waterat this point. Consequently, the water in the sink, washtub, orequivalent receptacle can escape only by overflowing at the upper end ofthe body 1. The lugs 11 not only center the rod 4:, and thus facilitatethe ready application of the device in a position for use, but they alsoprevent any relatively large obstructions from clogging the drainageopening. It will also be apparent that in the embodiment shown, theparts may be readily dissociated for the purposes of cleaning orrepairs.

It will be understood that no specific description herein contained isintended to put any limitation upon the scope of the appended claimswhich does not inhere in the language thereof.
